81216 Thrust Ball Bearing | M / TN Types Available
The 81216 thrust ball bearing is a high-precision single-direction thrust ball bearing engineered for pure axial load operation. It features high structural rigidity, low friction and stable axial positioning, delivering smooth and dependable performance for low to medium-speed industrial machinery. Available in 81216M and 81216TN cage types, this bearing offers durable, cost-effective thrust support for general mechanical transmission systems.
81216 M / TN Type Differences
81216M: Built with a solid machined brass cage with high rigidity, excellent heat resistance and strong impact tolerance. It maintains minimal wear and stable performance during long-term continuous operation, ideal for heavy-load, high-temperature and harsh industrial working conditions.
81216TN: Equipped with a lightweight nylon TN cage with low friction coefficient and quiet rotation. It provides reliable anti-fatigue performance and high cost efficiency, perfectly suited for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81216 thrust ball bearings adopt premium GCr15 high-carbon chromium bearing steel. Professional heat treatment grants high hardness, exceptional wear resistance and stable fatigue resistance to raceways and steel balls, ensuring long-term precise operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81216 bearings deliver superior rust-proof, anti-oxidation and weak corrosion resistance. They adapt perfectly to humid, dusty and sanitary working scenarios, preventing premature bearing damage and extending overall service life.
Product Features
Stable single-direction pure axial load capacity. High-precision axial positioning with low running noise. Two cage designs meet diverse speed and load demands. Excellent hardness and wear resistance prolong service life. Compact space-saving structure with outstanding cost performance.
Application Scenarios
81216 thrust ball bearings are widely used in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81216M fits heavy-load and harsh working environments; 81216TN suits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
